Brainstorm Electronics VSG-4
Video Sync Generator Card

OUR PART #  VSG4


The Brainstorm Electronics VSG-4 generates analog tri-level and bi-level sync signals for HD and SD video applications. It's designed as an option for the DCD-8 Word Clock Distripalyzer. The combination of the DCD-8 and the VSG-4 delivers a complete solution for all sync requirements in the post-production, recording and broadcast environments.

Up to 4 different sync formats can be generated simultaneously through the 4 BNC outputs, 2 HD and 2 SD. The VSG-4 operates either as a master sync generator or genlocked to any of the references available to the DCD-8: Video (HD or SD), Word Clock, Digital Audio (AES/EBU, S/PDIF, FireWire, ADAT) or GPS.

When genlocking, the output rates can be different from the reference rate, while still maintaining phase coherence. For example, 30 and 24 or 23.976 and 29.97 will be correctly aligned.

By making use of the DCD-8's B Domain PLL, the VSG-4 provides stable HD clock rates over long periods of time.

The VSG-4/DCD-8 combination brings a great amount of flexibility. Audio can be locked to video or vice-versa. Many different rates can be generated simultaneously. Most importantly, a single sync reference can run your whole audio/video installation.
